Abstract

The method relates to early recognition and prevention of sticking during the strip-casting of metals, in particular aluminium and aluminium alloys. The strip movements in the region between the roll gap (W) and the first deflection roller (46), in the vertical direction with respect to the strip surface (42, 44), are measured continuously or quasi-continuously and process parameters are changed by program control upon occurrence of vibrations. With the detection of this microsticking, process parameters can be changed before damage is caused due to sticking. <IMAGE>
